Hikari Kokura, a first-year Chidori High student, channels a fiery passion for beam-rifle shooting honed since childhood. Her quest to join the school’s renowned rifle club crumbles when she finds it disbanded, prompting her to rally three unlikely allies: childhood confidant Izumi Shibusawa, former middle school rival Erika Meinohama, and enigmatic marksman Yukio Igarashi.

Though academically shaky—requiring Izumi’s cram sessions to clear entrance exams and preserve club eligibility—Hikari oscillates between lax study habits and bursts of intense focus, proving her competence when stakes rise. Her breezy, impulsive charm masks a growing sense of duty as she mediates clashes between the team’s clashing temperaments.

A crimson ribbon crowns her youthful silhouette, contrasting a curvaceous frame often shrouded in baggy uniforms. She navigates relationships with tactical warmth: leaning on Izumi’s steadfast support, trading barbed yet good-natured taunts with Erika, and chipping away at Yukio’s stoicism with unyielding optimism.

Once a solo junior tournament contender who once outpaced Erika, Hikari now grapples with leading a team. Her scatterbrained pratfalls during practice dissolve into razor-sharp precision during competitions, reflecting her dual nature. Through mishaps and milestones, she stitches their fractured group into a cohesive unit, leveraging relentless cheer to bridge rivalries and forge camaraderie.
